Still waiting for conclusion after 6 years!!!!!

Overcharging dating back 6 years, where Neotel has not sent bills, final demands, requests for payment, or made any other form of collection effort, yet they list the account on Transunion as default payers every month for 6 years. every time we have contacted them they agree that the amount should be credited and then never do so. Until last year when they credited a \pro rata' portion of the month due to the finance department finding record of usage and within 10 days the IT department could not find the records as they have changed systems over the years!!! <br> E-mail 10/06/2014<br> Service request: SREQ_***<br> full credit could not be processed as our Finance deparment picked up usage on the month of November 2009 <br> E-mail 18/06/2014<br> Service request: SREQ_***<br> IT support could not trace the detailed data usage for 2009 as you requested as they advice number *** is an old number which was created and terminated on their old billing system and new system is now used<br> <br> After 6 calls being cut off after 25 min waiting on hold I am resorting to other methods. Ashford was to get back to me hours ago with a resolution to this 6 year old issue. I am still waiting. <br> "
